Description
Technical field
The present invention relates to thermal power plant's pollutant disposal system, the energy-saving combustion gas of specially a kind of utilization thermal power plant used heat is dirty
Contaminate thing processing system.
Background technology
Raising with China to fossil-fuel power plant atmospheric pollutant emission standard, it is all it is newly-built, building and active service fired power generating unit
It is required for using advanced flue gas cleaning draining technology to realize the minimum discharge of atmosphere pollution.According to existing technology water
It is flat, cooled down based on flue gas and the flue gas pollutant collaboration handling process of thermal technology is acknowledged as that the ultralow row in coal-burning power plant can be realized again
The main technological route put.
Its operation principle is that flue gas cooling and thermal technology again include two air-water heat exchangers, and one is gas cooler,
It is usually located on the flue between air preheater and electrostatic precipitator, flue gas heat is absorbed to reduce flue-gas temperature by WATER AS FLOW MEDIUM,
Purpose is reduction flue-gas temperature to reduce flue gas volume flow, reduction fan energy consumption, improve ESP Efficiency and three oxygen
Change sulfur removal rate；Another is smoke re-heater also referred to as flue gas heater, is usually located at wet desulphurization device or wet type electricity is removed
On flue between dirt device and chimney, in this heat exchanger, the high-temperature medium water discharged with gas cooler is heated after desulfurization
Or the cold flue gas after wet dedusting, corroded and " white cigarette " with improving atmosphere hoist height, reducing chimney by improving flue-gas temperature
Generation, after high-temperature medium water heat release temperature reduce, return gas cooler absorb high-temperature flue gas in heat, realize heating agent
The transmission of the interior circulation and flue gas heat of body.
Cooled down based on flue gas and the idiographic flow of the flue gas pollutant collaboration handling process of thermal technology is again：It is cold into flue gas
But the flue-gas temperature of device is cooled to 90 DEG C or so, medium by 70 DEG C or so of WATER AS FLOW MEDIUM at 130 DEG C or so in gas cooler
The flue gas that coolant-temperature gage rises to 100 DEG C or so, 90 DEG C or so enters electrostatic precipitator, wet desulphurization device, wet electrical dust precipitator
Temperature is further reduced to 50 DEG C or so rear entrance smoke re-heaters, in smoke re-heater, 100 DEG C or so of WATER AS FLOW MEDIUM heat release afterwards
Temperature is down to 70 DEG C or so and is pumped back to gas cooler by supercharging afterwards, and the release of 50 DEG C or so of smoke absorption WATER AS FLOW MEDIUM
Heat be warming up to 80 DEG C or so it is rear by smoke stack emission.
In fired power generating unit oepration at full load, because the exhaust gas temperature flowed out from air preheater is higher in 130 DEG C, flue gas
The heat that cooler absorbs disclosure satisfy that the heat needed for flue gas reheat heat exchanger.When fired power generating unit is in oepration at full load but
Under the climatic environments such as winter from air preheater outflow exhaust gas temperature is relatively low or fired power generating unit non-oepration at full load cause from
When air preheater flows out relatively low exhaust gas temperature and exhaust gas volumn reduction, due to gas cooler and the exhanst gas outlet of smoke re-heater
Temperature need to maintain with full capacity when close state, therefore the heat of gas cooler acquisition can not meet smoke re-heater
Need, the heat medium water of a certain amount of, certain parameter the steam heating gas cooler outflow of supplement is now usually required, to ensure cigarette
The flue-gas temperature of gas reheater outlet reaches 80 DEG C or so.According to the practical operating experiences for the fired power generating unit that put into operation, work as thermal motor
Group load is lower, and the quantity of steam of required supplement is more, and the energy consumption of flue gas minimum discharge processing system is larger.With 600MW thermal motors
Exemplified by group, when unit is run under 75%, 50% and 35% load, the heat that need to be supplemented be respectively 1800kW, 9000kW and
9800kW.The consumption of steam be based on flue gas cool down and again thermal technology flue gas pollutant collaboration handling process main energy consumption it
One, therefore how to reduce based on flue gas cooling and the energy consumption of the coal steam-electric plant smoke pollutant disposal system of thermal technology again is current fire
One of main difficult technical that power plant faces.
